With the rate of technology adoption ever increasing, it's a wonder we haven't seen this already. The Gibson Robot Guitar ($TBA; Dec. 7) carries the tagline "All you have to do is play it." With a revolutionary mix of on-board processing, a data transmitting tailpiece, tune-control bridge, and Powerhead Locking Tuners, the guitar automatically stays in tune, and can move to an alternate tuning with the turn of a switch. So really, all you have to do is play. [Thanks, Zach]
